On the starboard side of the fire wall, adjacent to the start solenoid, there are a set of check valves. The one on the upper side leads to the emergency tank. The small rubber disk inside it has probably deteriorated resulting in a drop in emergency air when the engine is not running. Doug Sapp has the appropriate overhaul kit. It's any easy fix. ...Blitz Sent from my iPhone On Oct 29, 2011, at 7:28 PM, "Adrian Coop Cooper" wrote: > > I am unable to find the preferred pressure and acceptable decay rate (if any) for the air pressure on the emergency side of the air system.

It is a clamp mounted instrument. The different one is the clamp screw, loosen that, give the screw driver a light tap and lift the gauge out of the hole. I agree - zero leakage for the emergency system. It is a rerlatively small system and easy to find the leak source (or sources).

Take a close at the very small hole that is the input of the gauge and see if it full of rust and crud. It is a common problem and makes the gauge lag behind pressure changes. A small wire drill can be used to CAREFULLY remove the rust.
